GMAIL Unresponsive on: Stationversion 1.46.1

Gmail email won’t send when trying to respond to an email or sending a brand new email.

Once it freezes, there is a ‘please wait’ bottom left corner, once this disappears you’re not able to navigate the labels in Gmail to move to sent, drafts, etc. This becomes non response. I am forced to close the app, restart in order to navigate.

I am on a MAC OS Mojave v. 10.14.3

I am looking to abandon this for Shift - but I would really prefer to use Station - please help as a matter of urgency!

Thank you
